First, the construction of mobile housing. Moving housing, in fact, is an easy-to-remove, easy-to-move shed constructed from bamboo, wood, and thin-film materials. It can be constructed on the spot: 1 It is 8 meters long, 1.2 meters wide, and tall with large bamboo or wooden strips. 2.2 meters frame. And in the middle open a door (width 0.8 meters, both sides without a window); 2 with the old fishing net around and the top of the surrounding, fixed, and covered with a thick black film; 3 sheds floor with bamboo or branches at 1 cm intervals laying Afterwards, the bottom of the pen is raised by 10-15 cm with bricks. The places where the pens should be placed should be selected on the grassy slopes that are sheltered from the wind, have a flat surface and do not accumulate water, and there should be forests or orchards next to them so that the birds can enjoy shade in the sun when the sun is strong, and there must be a flat and wide area. In the area, it is best to have plenty of grass and sand to allow chickens to freely inhabit and feed. Second, grazing rearing. According to the climatic conditions of the grazing land and weather conditions, the chickens were raised to about 30 days of age, and grazing was started when the body weight was 0.35-0.4 kg. It is also possible to purchase bred chicks for grazing and feeding directly from a large brooding farm. In order for the chicken to reach the market standard of 1.2 to 2 kilograms for 100 to 120 days of age, full-priced feed should be provided at the time of stocking. Reference formula: corn meal 57.7%, bran 14%, dry cake powder 18%, fishmeal 6%, bone meal 2%, shell powder 2%, salt 0.3%. A small amount of green feed should be added to the feed to prevent the birds from eating green feed when they are grazing. Feeding during the stocking period should be "early, early, and late, and appropriate in the evening," while taking into account the characteristics of poor feeding ability of young chicks and feeding as appropriate. To do less ground Tim Tim, avoid leftovers in the tank in order to avoid deterioration caused by disease. When stocking, it is necessary to pay attention to grouping the chickens according to their strengths and weaknesses and stocking them in batches. The size of stocking is generally appropriate for 800-1000 eggs per group. Select the sunny and warm weather to try it out. The start time is shorter, and gradually extend later, so that the chicken can gradually adapt to grazing and feeding. Grazing sites should be near and far, and the scope gradually expanded. However, the range of activities for grazing chickens should not be too large in order to increase the feed efficiency of chickens. Can be separated by a wire fence, which not only limits the range of activities of chickens, but also facilitates rotational grazing. It can also prevent chickens from fleeing and wild animals from invading. In the process of grazing, special grazing should be conducted to pay close attention to the weather conditions. In the event of abrupt changes in the weather, the chickens should be rushed back to the pens before the heavy rain, snow, and windy weather to prevent chickens from being caught in cold and cold. Hot days of stocking should be released sooner or later, at noon in the shade or back to the shed, to avoid long-term exposure under the sun exposure, to prevent heat stroke. In addition, in order to improve the chicken's own resistance, in the breeding process, attention should be paid to doing a good job of sanitation, keeping the house clean, dry and well ventilated. Drinking water, feed, utensils and litter are clean; adopt the "all-in, all-out" feeding method. Keep the appropriate temperature, humidity and flock density in the house. Stepping up patrols and observations, we found that sick and weak chickens who are slow in action, alone, and listless are to be treated in time. Third, prevention and disinfection. Chicks were injected with Marek's vaccine at 1 day of age, Newcastle disease II + H160 was injected at 9 days of age, 14 days old French vaccine was given 2 times water, and 25 days old was injected with Newcastle disease oil vaccine, 50 and 80 days old. Each E. coli vaccine was injected once and comprehensive immunization was performed for each batch of chickens. Thoroughly clean and disinfect after each batch of chickens are sold. Fourth, pay attention to matters. After the chicken has moved three rounds of chickens, the stalls will be moved to another new place. This will not only effectively reduce the chances of infection between chickens, but also reduce the “pastoral†pests and diseases through the activities of the flock. During the rearing period, yellow corn or yellow pigment feed should be fed to make the carcasses appear yellow. With the increase in the age of chickens, the tender and succulent meat will be getting worse and worse. It is necessary to sell the meat as soon as possible to ensure the quality of the meat.
